Hal and Sal need to make $500 in sales to have their pay equal. Their gross pay will be $350 each.

To find the amount of sales that Hal and Sal need to make their pay equal, we can set up an equation.

Let's say the amount of sales that Hal needs to make is x.

Hal's base wage is $150 per week, and he also earns a 40% commission on total sales. So his total pay can be expressed as:

Total Pay = Base Wage + Commission

Total Pay = $150 + (40% * x)

Similarly, Sal's total pay can be expressed as:

Total Pay = $175 + (35% * x)

To find the amount of sales that makes their pay equal, we can set these two equations equal to each other:

$150 + (40% * x) = $175 + (35% * x)

Now we can solve for x:

$150 + 0.4x = $175 + 0.35x

0.4x - 0.35x = $175 - $150

0.05x = $25

x = $25 / 0.05

x = $500

So, to make their pay equal, Hal and Sal both need to make $500 in sales.

To find their gross pay, we can substitute the value of x into the equations for their total pay:

Hal's Gross Pay = $150 + (40% * $500) = $150 + $200 = $350

Sal's Gross Pay = $175 + (35% * $500) = $175 + $175 = $350

Given:

The radius of each small circle = 3 ft

The area of the given space = 100 ft

To find the number of circles could fill the space of 100 ft.

Formula

The area of a circle is

[tex]A = \pi r^{2}[/tex], where r be the radius of the circle.

Now,

Putting, r = 3 and π = 3.14 we get,

[tex]A = (3.14)(3^{2} )[/tex] sq ft

or, [tex]A = 28.26[/tex] sq ft

So, the area of each circle is 28.26 sq ft

Now,

Number of circles that could fill into the given space = 100÷28.26

= 3.53≈3

Hence,

3 circles with radius 3 ft could fill a 100 sq ft space without overlap.

Answer:

5 and 5

Step-by-step explanation:

Since your shape is a square, ALL SIDES HAVE TO BE EQUAL. So 5x5 equals 25.

If the sum of the squares of two numbers is 50 and the product of the two numbers is 25, then the two numbers are 5 and -5.

Let's assume the two unknown numbers are "x" and "y". We are given two conditions:

The sum of the squares of the two numbers is 50:

This can be represented as an equation: x² + y² = 50.

The product of the two numbers is 25:

This can be represented as another equation: x * y = 25.

Now, we have a system of two equations with two variables (x and y). We can solve this system of equations to find the values of x and y. Let's use the substitution method to do this.

Step 1: Solve one equation for one variable in terms of the other variable.

From the equation x * y = 25, we can solve for y in terms of x:

y = 25 / x.

Step 2: Substitute the value of y in terms of x into the other equation.

Replace y in the equation x² + y² = 50 with 25 / x:

x² + (25 / x)² = 50.

Step 3: Simplify and solve the equation for x.

x² + 625 / x² = 50.

To eliminate the fraction, multiply both sides by x²:

x⁴ + 625 = 50 * x².

Rearrange the equation to bring all terms to one side:

x⁴ - 50 * x² + 625 = 0.

Step 4: Solve the quadratic equation for x.

This is a quadratic equation in terms of x². Let's substitute a new variable to simplify the equation. Let u = x². Now the equation becomes:

u² - 50 * u + 625 = 0.

This quadratic equation can be factored as:

(u - 25)² = 0.

Solving for u:

u = 25.

Step 5: Find the values of x and y.

Now that we know u = x² = 25, we can solve for x and y:

x² = 25,

x = ±√25,

x = ±5.

And since x * y = 25, when x = 5, y = 25 / 5 = 5.

When x = -5, y = 25 / -5 = -5.

To identify the shaded part of a 100 grid as a fraction, count the shaded squares; each represents 1%, making the denominator 100. The fraction formed can be simplified if possible, and converting it to a decimal involves dividing the numerator by the denominator.

To identify the shaded part of a 100 grid as a fraction and a decimal, you must first count the number of shaded squares. Since each square represents 1% of the total grid, the number of shaded squares can be directly written as a percent. For example, if 45 squares are shaded, the shaded part would represent 45%.

As a fraction, this is equal to 45/100, because the denominator should be 100 in order to represent a percent as a fraction.

To convert this fraction to a decimal, divide the numerator by the denominator which gives 0.45. If you have shaded half the grid, it means 50 squares are shaded out of 100. The fraction would therefore be 50/100, which simplifies to 1/2, and the decimal would be 0.50.

Answer:

676000

Step-by-step explanation

3 digits of the 5-digit code are number 0-9 which is 10 numbers that could go into that spot, after the three digits there are two letters and because there are 26 letters in the alphabet you would multiply 10*10*10*26*26 which equals 676000

There are 676,000 possible codes.

An arrangement of objects where the order in which the objects are selected does not matter.

Given that  library labels each book with a five-digit code to identify the books in their computer system.

Each code is 3 digits (0-9) followed by two letters

We need to find the possible number of codes.

There are 10 possible digits (0-9) for each of the first three positions, and 26 possible letters (A-Z) for each of the last two positions. Therefore, the total number of possible codes is:

10 x 10 x 10 x 26 x 26 = 676,000

Hence, there are 676,000 possible codes.

Answer:

147, 148

Step-by-step explanation:

295/2=147 remainder 1 so, consecutive means back to back so 147 and 148. Add them up and you get 295.

Final answer:

The consecutive page numbers with a sum of 295 are 147 and 148, with 147 being the left page and 148 being the right page.

Explanation:

To find the consecutive page numbers of an open book with their sum equal to 295, we can set up a simple equation. Let the smaller integer be n, which means the next consecutive integer (the other page number) would be n+1. Since their sum is known to be 295, we set up the equation as n + (n + 1) = 295.

Solving for n gives us:
n + n + 1 = 295
2n + 1 = 295
2n = 294
n = 147

Therefore, the two consecutive integers are 147 and 148. The left page number is 147 and the right page number is 148.

Answer:

C) 8w = 80;30  

This is because it is a rectangle and 30ft +30ft =60ft length.

The question asks to make the fence as large as possible  fencing overall is same ratio as D but more for length.

The new equation could be for total width both sides;

           9^2 -1w = 5

               81-1w = 5

                     w = 80/5

                     w = 16ft

Final answer:

To calculate the largest possible length for Lance's chicken fence, set up the perimeter equation with length as three times the width. The equation simplifies to 8w=80, and solving for w gives a width of 10 feet, making the largest possible length 30 feet. The correct answer is option C.

Explanation:

Lance is building a rectangular fence for his chickens, and he wants the longer side, the length, to be three times the shorter side, the width. The total amount of fencing he has is 80 feet. To find the largest possible length, we need to set up an equation.

Let the width be w. Then, the length will be 3w. The perimeter of a rectangle is calculated by the formula P = 2l + 2w, where P is the perimeter, and l and w are the length and width, respectively. Since he has 80 feet of fencing, the equation is:

2(3w) + 2w = 80

Simplify the equation:

6w + 2w = 80

8w = 80

To find the value of w, divide both sides of the equation by 8:

w = 80 / 8

w = 10

Now that we have the width, let's find the largest possible length:

Length = 3w = 3(10) = 30

Therefore, the largest possible length is 30 feet. The correct choice is C) 8w=80; 30.

Option 2. the circle graphs are not functions when there are two arrows pointing on the same right number

Answer: The dimesions will be decreased by 13.05%.

Step-by-step explanation:

Hi, we have to calculate the original area.

Area of a rectangle = Length x width

Replacing with the values given:

A = 40x50 = 2000 ft2

Since is reduced to 1739. if we multiply the original area by a the percentage decrease, and subtract that value to the original area, we obtain 1739 ft2.

2000 - (2000x) = 1739

Solving for x

-2000x = 1739 -2000

-2000x = -261

x =-261/-2000

x = 0.1305

Multiply by 1000 to obtain the percentage:

0.1305 x 100 = 13.05%

So many more, but here are a few.

To find three numbers that add up to 30, you can choose different combinations. For example, you could use 10, 10, and 10 or figures like 15, 10, and 5. The specific numbers can vary based on the criteria involved.

When dealing with numbers that add up to a specific value, there are many possible combinations depending on the criteria you use. For example, if you wish to find three different positive numbers that add up to 30, you could choose 10, 10, and 10. This is because each number is significant and can be repeated in this scenario. These would add up to 30, as 10+10+10 equals 30.

Alternatively, you could choose a variety of numbers such as 15, 10, and 5, which also add to 30. Here the expression is set up as 15 + 10 + 5. Another option could be three unit conversion factors like 12, 8, and 10. The method of finding three numbers that add up to a certain sum is an extension of practical problem-solving often used in daily life.
